    Géraldine Texier is  a professor at the Network Systems, Cyber Security and Digital Law (SRCD) department at IMT Atlantique and a member of the Adopnet research team from IRISA. She is working in the Advanced Connectivity lab of the b<>com Institute of Research and Technology. In 2016-2017, she was a visiting researcher at INRIA@Silicon Valley, CITRIS, University of California, Campus of Berkeley where she worked on routing for IoT in Smart Cities.

    She received her Ph.D. on distributed systems and especially on cooperation and awareness management in computer supported collaborative work (CSCW) in 2000 from the University of Rennes 1 in France. She defended her Habilitation à Diriger des Recherches (HDR) "Vers un Internet programmable offrant des garanties de qualité de service." on the 3rd of December 2019 at University of Rennes 1. 

    Her current research activities are focused on network virtualization, routing and QoS in communication networks and especially on slice placement in 5G networks.
